To all whom it mag concern.-

Be it known'that'I, EUGENE SCHNEIDER, a'citizen of the French Republic, and a resident of 421Rue "dAnjou, Paris, France, have invented new and useful Improvements in Apparatus for'Operating Valves of Engines 'andthe'like, which invention is fully 'set forth in the following'specification.

This invention has for its ob-ject to provide an improved apparatus "for operating a plurality of valves (such as the valves of engines and the like) by a common member, such as for instance a lever or a rocking beam.

The improved apparatus in operating all the valves simultaneously, assures absolutely uniform amounts of lift and avoids all jamming of the valve stems in their guides.

For this purpose, tion, the mechanism connecting the valves tobe operated and the common operating member, comprises a part which has, according to the number of valves to be operated, for instance the shape of a crosshead,

carrying in all cases for each valve a proecting supporting finger-which is adjustable and centered in the corresponding valve stem. This finger carrier .issu-itably guided by two axial projections in a box formed on or fixed to the valve box, which limits its movements. Between these guiding projections, abutments are provided for the support of the end of the actuating rocking beam.

According to one embodiment of this invention the lower bearing or abutment of the rocking beam upon the finger carrier is provided by means of a block that is jointed to the end of the lever and has its underside adapted to be supported and to slide upon the faced surface of a bearing piece fixed in an axial lodgment in the said finger carrier.

This constructional form of the improved apparatus is illustrated in detail in the accompanying drawings in which:

Figure 1 is a vertical section partly in elevation,

Fig. 2 is a horizontal section on the line IIII of Fig. 1, and

Fig. 3 is a partial cross section on the line III-III of Fig. 1, of the said constructional form applied for the simultaaccording to this invenan axle pin 0 at the ends of neous operation of two valves by means of 'a common rocking beam.

the motion that is imparted to it by the engine.

The connection between the arm C of the rocking beam and the valve stems a, is provided according tothis invention by. a part F which isflguidedby projections-F F in aguide that isj'formed on .or-fixed to the valve boxes. This guide for the sake of facility iii-erection is-preferablymade of two superposedparts Gr, H- connectedhand fixed to the valve boxes by bolts I.

"The arm C of the rocking beam termi nates at its free end in a fork 0 carrying on which is pivoted a block which with its faced surface 7' bears and slides upon a corresponding faced surface 70 of a bearing piece K fixed in the part F.

The said part F carries as many fingers f as there are valves to be operated (namely two in the example shown in Figs. 1 and 3, and four in the example shown in Fig. 4). These fingers f are formed at the ends of screw-threaded rods engaged in corresponding internal screw-threads formed in the part F. The fingers f may be located the arms for facility in construction and guidance. Each of these fingers which bears upon the head of the stem of the respective valve, is centered in the latter by means of a nipple f The amount of projection of the finger beyond its supporting arm may be adjusted by means of the nut f It will be perceived that the rocking motion of the rocking beam C in the requisite direction, will cause the finger carrier F to move down by the action of the block J, and consequently will cause the valves to be opened by the fingers ff bearing upon their stems. In the rocking movement of the rocking beam C-C in the opposite direction, the action of the said rocking beam upon the finger carrier F and the valves does not take place. The valves are returned on to their seats by their springs which moves at the same time the finger carrier back into its initial position.

he finger carrier F is accurately centered in its guide G-H by the projections F F and will therefore execute a perfectly rectilinear movement and will produce in its turn a strictly rectilinear motion of the valve stems.

In the example shown in Fig. 4, the part F has four arms the free ends of which carry the bearing fingers f projecting to an adjustable amount, each finger being centered by means of a nipple 7' in its respective valve stem.

What I claim is 1. In an apparatus for operating a plurality of valves, such as engine valves and 1 others, by means of a common operating member, such as a rocking beam, the combination with said common operating member, of means constituting a connection between the latter and the stems of the valves to be operated, comprising-a finger-carrier, a plurality of adjustable fingers on said carrier equal to the number of valves to be operated, means for adjusting the projection of said fingers, a centering member on each of said fingers engaging in and centering the respective valve stem, guides on'the valve boxes, oppositely located axial proj ecting members on said carrier working in Copies of this patent may be obtained for said guides,

to be'operated, comprising'a finger-carrier,

a plurality of adjustable fingers on said carrier equal to the number of valves to be opperated, means for adjusting the projection of said fingers, a centering member on each of said fingers engaging in and centering the respective valve stem, guides on the valve boxes, oppositely located axial projecting members on said carrier working in said guides, a block pivoted on the end of the rocking beam, having a faced bearing surface, and a bearing member in said carrier, having a faced pressing surface cooperating with said faced bearing surface, whereby said carrier is actuated to operate the valves by the sliding pressure of said faced pressing surface on said faced bearing surface.

In testimony whereof I have signed this specification.
